HILLSIDE OR REVERSIBLE-PLOW.

SPECIFICATION forming part of Letters Patent No. 651,578, dated June 12, 1900.

7 Application filed March 10I 1900. Serial No. 8,216. (llo model.)

To all whom it may concern.-

Be it known that LJAMES R. MOWANE, a citizen of the United States,residing at Lynchburg, in the county of Campbell and State of Virginia, have invented a new and useful Hillside or Reversible Plow, of which the following is a specification;

This invention relates to hillside or reversible plows, and particularly to the moldboards used in plows of this character; and it has for its object to construct a moldboard with a detachable pivotal socket-piece :for receiving the usual standard on wh'ich'the moldboard is mounted and turns, whereby the body of the moldboard may be used for an indefinite time.

Nearly all hillside or reversible plows are constructed with the standard entering a socket on the moldboard, and heretofore the socket has been formed in the integral portion of the moldboard at the point thereof. There is a serious disadvantage in having the socket for the standard formed in an integral portion of the moldboard at'its front end, because when the point of the plow com mences to wear this point of the moldboard is letdown on the ground and wears out very rapidly, and in the course of time will wear away the metal down to the hole or socket in which the standard of the plow enters, thereby allowing the standard to drop out of the socket entirely, and thus necessitating an entirely new moldboard being fitted to the plow. The improvement contemplated by the present invention obviates the objection to having the socket for the standard formed in an integral portion of the moldboard by using in connection with the moldboard a separate detachable socket piece, which socket-piece is located at the point where the greatest wearing action occurs and which can be readily removed and replaced when,

worn out at a nominal expense in comparison with the cost of a new moldboard. The essential and leadin g feature of the present invention is therefore the provision of the moldboard of a reversible plow, at the point thereof, with a detachable socket or pivotal piece, and while the invention in this aspect is necessarily susceptible to a variety of 1nodi fications, especially as to the particular manner of connecting the detachable socket-piece plated by the present invention.

moldboard.

with the moldboard-body, still the preferred embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a perspective view of a hillside or reversible plow whose moldboard is fitted with the detachable pivotal piece con tem- Fig. 2 is a rear perspective view of the moldboard with the socket-piece fitted thereto. Fig. 3 is a sectional view on the line 3 3 of Fig. 2. Fig. 4: is a similar view on the line at 4 of Fig. 2. Fig. 5 is a reverse plan view of the point end of the moldboard, exposing the formation of the socket-seat. Fig. 6 is a detail in perspective of the detachable pivotal socket-piece, showing the reverse side thereof that matches with the seat formed at the pointend of the Referring to the accompanying drawings, 1 designates an ordinary hillside or reversible plow havingv the usual reversible lnoldboard 2 and the standard 3, on which the moldboard is mounted and turns, and said moldboa -rd 2 is provided in its working face, at the point end thereof, with the usual seat at for'receiving the share or detachable point, andin the present invention the moldboard is provided at its front end, on the rear side thereof, with a cut-away portion 5, forming a seat, in which is adapted to register the detachable socket- -piece or block 6, which forms a member of the pivotal connection between the moldboard and the standard. I

The moldboard 2 is formed atits pointend with the usual V-shaped portion 7, which is thickened somewhat in the form of a truncated pyramid, and the socket-receiving seat 5 is formed directly in the said thickened portion 7, so that when the detachable socketpiece 6 is placed in said seat the same will match with the portion 7 and form a complementary part thereof, so as to maintain the common outlines or shape of the moldboard at its point end.

The socket-receiving seat 5, formedin the inoldboard, is provided with a substantiallyflat face or base, provided with a separate alternately-arranged locking projection anddepression 8 and 9, respectively,'and at the front end of said seat 5 is located an abutting shoulder 10, provided therein with a lockingrecess 11, adapted to receive therein a rounded lobe 12, formed at the nose or point end placement or disarrangement of the socketof the detachable socket-piece 6. The detachablesocket-piece 6 is also of approximately truncated pyramidal shape,and in addition to the lobe or projection at the front end is provided at its inner side with a looking projection 13 and a looking depression or cavity 14:, alternately arranged and respectively interlocking the corresponding projection and depression 8 and 9 in the base of the seat 5, so that when the socket-piece is fitted in the seat 5 it is held by the interlocking portions from displacement in a lateral di rection even though the securing means for the socket-piece should become loosened.

One method of detachably securing the socket-piece to the moldboard is shown in the drawings, and this consists in providing the socket-piece with a threaded bolt-stem 15, projecting through a bolt-opening 17 in the moldboard and receiving a nut or tap 18 at the side of the moldboard opposite the socket piece. It will be understood, however, that other means may be resorted to for securing the detachable socket piece to the moldboard-such, forinstance, as providing the socket-piece with wings running out to the holes which are designedfor the bolts of the share orpoint and by making the bolts snfliciently long so that they can be utilized to fasten not only the point or share to the moldboard, but also the socket-piece. This manner of fastening the socket-piece in place will probablynecessitate a third bolt at the point where the bolt is shown in the drawings;but this would make the fastening much more Socure than the one already described.

The interlocking projections and depressions formed in the matching faces of the socket-piece and the seat for receiving the same are designed not only to prevent the socket-piece from working laterally, but also from working either backward or forward, and while the projections and depressions have been described as being arranged in a particular way it will be understood that such projections and depressions maybe reversed from the position already described and, in fact, located at any suitable point without departing from the spirit or scope of the invention, the purpose of such projections and depressions in all cases being to prevent dispiece in the event of the fastening or fastenings therefor becoming'loose.

Other changes in the form, proportion, and

minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, I

-i claim- 1 In a plow, a pivoted moldboard having a detachable pivot-piece for the standard, sub- 1 stantially' as described.

2. In a plow, a pivoted moldboard provided at its point end with a socket-seat, and a pivot-piece for the standard, detachably fitted in said seat, substantially as described.

3. In a plow a pivoted moldboard provided with a socke -receiving seat, a separate pivotpiece for the standard, registering with said seat, an interlockingconnection between the pivot-piece and seat, and fasteningmeans for detachably holding the pivot-piece in place, substantially as described.

4. In a plow, a reversible moldboard provided at its point end in the rear side there of, with a socket-receiving seat having looking projections and depressions,and a pivotpiece for the standard detachably fastened in said seat and having corresponding'projections and depressions interlocking with'those of the seat, substantially as described.

5. In a plow, the reversible moldboard provided atthe point end and in the rear side thereof, with a socket-receiving seat having a projection and depression in the base thereof and a recessed shoulder at its front end, a separatesocket-piece of a truncated pyramidal form, registering in said seat, and. havin g projections and depressions interlocking with the corresponding portions of the seat, and a bolt-fastening for detachably holding the socket-piece in place, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
